What term describes the rules or orders issued by an administrative agency of government that usually have the force of law?

The term that describes the rules or orders issued by an administrative agency of government, which typically have the force of law, is regulation. Regulations are formulated to enforce laws passed by the legislature and provide specific details on how the law is to be implemented and enforced. They serve as a critical mechanism for agencies to carry out their statutory mandates and ensure compliance with the law.

Unlike policies, which may outline broader principles or objectives but lack the binding authority of law, regulations are designed to set specific requirements that must be followed. Guidelines offer recommendations or best practices but do not carry legal enforcement implications. Procedures detail the steps to be taken to achieve a certain end and may be influenced by regulations but are not in themselves legally binding. Therefore, regulations are the definitive answer as they embody enforceable rules established by governmental authority.
